BOV Overfuelling Problem Fixed

G'day guys,

Came up with an idea that I have tested and works.

For all you people who have externally vented BOV it will stop your over fuelling and stalling.

What I did was run both the stock and an aftermarket BOV. I found that the aftermarket BOV was not venting as the stock valve was letting all of the air out before it reached the aftermarket one.

To alleviate this problem I placed a thin metal plate of the mounting for the original BOV (whre gasket is), then I drilled a drilled holes in the plate so it would limit the air going through the stock valve. This inturn let the stock valve vent under low boost back to the intake to stop the engine over fuelling. But when you hit full boost the aftermarket blows out a majority of the whilst the stock valve only lets out a small amount of pressure.

And if you call now, you will receive 2 packets of 2 minute noodles free!!!!!!

Thought this would help.

I pulled the peice of aluminium of a old camera that I was going to throw out. I drilled a hole with a size 12 dowel drill bit.

I am thinking of even going to a size 10 to see how it goes. Go samll and make the hole larger for your needs.

Just curious, but say you still have the stock BOV fitted and want to 'upgrade' Would it not be a good idea to shop around for a Hybrid kind BOV that vents both to Atmo and internally? You may not get as loud a "Pssssht" sound I suppose, but wouldn't that contribute to eliminating the mixture issue?

Also, would a SAFC correct the issue if you had a pure atmo BOV?

yes, an aftermarket computer will fix the iddle problem; such as S-AFC (even the early model AFC will do the job), Power FC. or you even can spend some money on iddle stablizer (not expensive though..), depands which way you want to go consider the $$ issue.

yes, you can get the hybrid of BOV, but chance is you don't like the sound, i.e. I like the sound comes from Blitz BOV, so I will try to have it installed and try to have stable iddle. btw, don't you know the blitz BOV will increasing 10rwkw? just j/k :mad:

This is basically for a mod for people who have externally vented BOV and have the shits all the time with bad idle, stalling, flame throwing etc. If you have a aftermarket plumbback no need the do this.

Beleive me, this works or not if you like stalling:D

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
